AT VANGUARD, WE BELIEVE THAT TRADITION MATTERS

Our 8,000 crew members embrace the traditional values on which our success is
built, including integrity, hard work, thrift, teamwork, and fair dealing on
behalf of our clients. 

This year, our report cover pays homage to three anniversaries, each of great
significance to The Vanguard Group:

- -  The 200th anniversary of the Battle of the Nile, which commenced on August 1,
   1798. HMS Vanguard, the victorious British flagship at the Nile, is our
   namesake. And its motto--"Leading the way"--serves as a guiding principle for
   our company.

- -  The 100th birthday, on July 23, of Walter L. Morgan, founder of Wellington
   Fund, the oldest member of what became The Vanguard Group. Mr. Morgan was
   friend and mentor to Vanguard founder John C. Bogle, and helped to shape the
   standards and business principles that Mr. Bogle laid down for Vanguard at
   its beginning nearly 25 years ago: a stress on balanced, diversified
   investments; insistence on fair dealing and candor with clients; and a focus
   on long-term investing. To our great regret, Mr. Morgan died on September 2.

- -  The 70th anniversary, on December 28, of the incorporation of Vanguard
   Wellington Fund. It is the nation's oldest balanced mutual fund, and one of
   only a handful of funds created in the 1920s that are still in operation.

   Although Vanguard constantly tackles new challenges, adopts new technology,
   and develops new services, we treasure the traditions and values that set us
   apart in a crowded, competitive industry. And we salute our shareholders,
   whose support and trust we strive to earn each and every day.

Low inflation and a general decline in interest rates made 1998 a rewarding year
for bond investors. Vanguard Total Bond Market Index Fund posted a strong +8.6%
return for the year, once again exceeding the return of its average competitor
and closely tracking its index benchmark, as it has each year since 1988. The
returns of our other bond index funds were similarly impressive, ranging from
+7.6% for our Short-Term Bond Index Fund to +12.0% for the Long-Term Bond Index
Fund.

</TABLE>

       The adjacent table presents the total return (capital change plus
reinvested dividends) for our funds during the past twelve months. Each is
compared with its average mutual fund peer and the unmanaged bond market index
it emulates. Each of our funds outpaced its average competitor and closely
tracked the return of its target index. Indeed, our Long-Term Bond Index Fund
surpassed its index benchmark. Because indexes are theoretical constructs
without the real-world expenses of fund operations and transaction costs, they
are tough standards for mutual funds to match, much less to outdistance.

       Detailed per-share figures for each fund, including net asset values and
income dividends, along with yield, credit quality, and maturity data, are
presented in the table that follows this letter.

FINANCIAL MARKETS IN REVIEW

The U.S. economy grew at a robust pace of more than 3% during 1998 as it
shrugged off the effects of serious financial problems in Asia, Russia, and
Latin America. Troubles abroad slowed demand for American exports and boosted
demand for imported goods, increasing the U.S. trade deficit. The Federal
Reserve Board cut short-term interest rates three times between September and
November, citing unsettled financial markets and unusual economic conditions.
But the domestic economy got a powerful push from higher consumer spending,
which was encouraged by low unemployment (4.3% at year-end) and higher wages (up
about 4%). Inflation remained quiescent, with consumer prices rising 1.6% for
the year.



                                       1
<PAGE>   4

       Interest rates declined on balance during 1998 and bond prices, which
move in the opposite direction from interest rates, generally rose. Price
appreciation accounted for 2 percentage points of the +8.7% total return of the
Lehman Brothers Aggregate Bond Index. U.S. Treasury bond prices benefited from a
"flight to quality" as many investors shunned riskier securities. The yield on
the benchmark 30-year U.S. Treasury bond began the year at 5.92%, fell to a
31-year low of 4.72% on October 5, then climbed back to 5.09% by year-end--down
83 basis points (0.83 percentage point) for the twelve months. Yields on 3-month
Treasury bills declined on balance during the year by 90 basis points to 4.45%
on December 31.

       While bonds generally enjoyed a strong year, the U.S. stock market
produced mixed results. Large-capitalization stocks, as measured by the Standard
& Poor's 500 Composite Stock Price Index, gained +28.6% for the year, despite a
sharp tumble in July and August. This result, however, masked weakness elsewhere
in the market. The Wilshire 4500 Equity Index, which comprises stocks not
included in the S&P 500, gained just +8.6%, while the small-cap Russell 2000
Index declined -2.5%. In the entire market, more stocks declined in price than
rose.

1998 PERFORMANCE OVERVIEW

The total return of any bond fund consists of interest income plus or minus any
change in the prices of securities held by the fund. During 1998, interest
income provided the majority of the total return for each of our bond index
funds, augmented by varying degrees of price appreciation. Each fund's current
yield at the end of 1997 and 1998 is shown in the following table, along with
the income and capital components of each fund's total returns.

       As this table makes clear, the longer a bond fund's average maturity, the
more sensitive its net asset value is to changes in interest rates. During 1998,
declining interest rates enhanced total returns, especially for bonds with
longer maturities. Of course, volatility is a two-way street, and during periods
when interest rates rise, bond prices will fall, offsetting at least to some
degree the interest income from the bonds. Over longer periods, however, a bond
fund's primary source of total return is the rate of interest income--or
coupon--of its underlying bonds.

       Our total returns were well in excess of those earned by competing bond
funds with similar average maturities and credit quality. The margins of
superiority were 0.9 percentage point for our Total Bond Market Index Fund; 1.3
percentage points for our Short-Term Bond Index Fund; 2.4 percentage points for
our Intermediate-Term Bond Index Fund; and 3.9 percentage points for our
Long-Term Bond Index Fund. This performance is due partly to our low operating
costs and partly to the fact that professional managers not only have difficulty
in forecasting interest rates, but incur significant research and transaction
costs in their efforts to outshine the bond market itself.



                                       2

       We note that our peer fund groups--all in the government bond fund
category--are not a perfect match for our funds, which hold more corporate bonds
than many competitors. For example, the Total Bond Market Index Fund invests
about 30% of its assets in the debt securities of industrial, financial, and
utility companies. This was a disadvantage for us in 1998, when corporate bonds,
especially in the long- and intermediate-term maturity ranges, fared less well
than comparable U.S. Treasury and government agency securities. Over time,
however, higher-yielding corporate holdings should enable our funds to provide
higher returns than funds that invest exclusively in government bonds.

       U.S. Treasury and federal agency securities make up the majority of the
holdings in our Short-Term, Intermediate-Term, and Long-Term Bond Index Funds.
The Total Bond Market Index Fund, while holding about 28% of assets in
Treasuries and other agency securities, also invests about 33% of assets in
GNMAs and other mortgage-backed securities. Mortgage securities are backed by
federal guarantees against the loss of principal or interest payments, but they
are vulnerable to "prepayment risk"--the possibility that homeowners will pay
off loans early to refinance at lower rates when interest rates decline. When
prepayments rise, as they did in response to lower interest rates in 1998,
investors receive a smaller-than-expected overall return. To compensate
investors for prepayment risk, mortgage-backed securities carry higher yields
than comparable Treasury securities. During 1998, however, their higher yields
could not lift mortgage-backed securities to higher returns than those earned by
comparable Treasury securities. The Lehman GNMA Index earned a +6.9% return for
the year, compared with the +11.6% total return for the Lehman 5-10 Year U.S.
Treasury Index.

       The Fund Profiles starting on page 8 list each fund's average duration,
an indication of how much a bond fund's share price will move in response to
changing interest rates. For example, if a bond fund's average duration were 7
years, its share price would fall about 7% for each percentage-point rise in
market interest rates. Conversely, if market rates declined by a percentage
point, the share price of a bond fund with an average duration of 7 years would
rise by about 7%.

LONG-TERM PERFORMANCE OVERVIEW

Vanguard Total Bond Market Index Fund was established in December 1986 as the
nation's first bond index fund for individual investors. Since its creation, the
fund has achieved a sizable return advantage of 1.2 percentage points annually
over funds holding securities of comparable maturity ranges and credit quality.
This margin has amounted over the past decade to an extra return of $2,481 on a
$10,000 investment in the fund versus an identical investment in its average
competitor, assuming reinvestment of income dividends and any capital gains
distributions. This extra return is nearly one-fourth of the initial investment.

       Our low costs are a key factor in this advantage. The annual expense
ratio of the Total Bond Market Index Fund is 0.20%, or $2 per $1,000 in assets,
about one-fifth the 1.06% expense ratio ($10.60 per $1,000 in assets) of its
average peer. Because operating 



                                       3

costs directly reduce the income that bond funds pass along to their
shareholders, our expense advantage of more than 0.8 percentage point gives us a
big head start every year in our effort to outperform peer funds.

 *March 1, 1994, for the Short-Term, Intermediate-Term, and Long-Term Bond
  Index Funds; September 18, 1995, for the Institutional Shares of the Total
  Bond Market Index Fund.

**Minimum initial investment is $10 million.

       As low as they are, our costs make it difficult to match the return of
the cost-free Lehman Aggregate Bond Index. The small gap--much smaller in recent
years than in the early years--between our fund's return and that of the index
stems almost entirely from the operating and transaction costs that we incur.

       Our other bond index funds are less than five years old, but already have
established a record of soundly outperforming their peers and closely tracking
their target indexes. The adjacent table shows the average annual return for
each fund from its inception through year-end 1998, along with the growth of a
hypothetical $10,000 investment in the fund. The same data are presented for
each fund's average competitor and target index.

       Based on initial $10,000 investments, the additional returns earned for
shareholders by our funds have ranged from $636 for our Short-Term Bond Index
Fund to $2,388 for the Long-Term Bond Index Fund. The Short-Term,
Intermediate-Term, and Long-Term Bond Index Funds all operate at the same 0.20%
annual expense ratio as the Total Bond Market Index Fund. (The expense ratio of
the Institutional Shares of the Total Bond Market Index Fund is 0.10%, or just
$1 a year per $1,000 in assets.)

IN SUMMARY

Events during 1998 provided an ample demonstration of the important role bonds
can play in a balanced investment portfolio. Bond funds can help to cushion the
anxiety arising from extreme fluctuations in the stock market. In addition, bond
funds can be a reliable source of current income, though share prices are still
subject to volatility due to changes in market conditions.

       We have always believed that investors are well served by selecting a mix
of stock funds, bond funds, and money market funds appropriate to their
investment time horizon, goals, and risk tolerance, and then sticking with their
plan. The Vanguard Bond Index Funds provide a low-cost, well-diversified means
of implementing the fixed-income portion of such a plan.

Vanguard Bond Index Funds. We shortened each name and replaced "portfolio" with
"fund" as part of a broader effort to clarify the names in our fund lineup.

THE MARKETS IN PERSPECTIVE
YEAR ENDED DECEMBER 31, 1998

[PHOTO]

Financial markets continued to produce solid overall gains during 1998. After
overcoming a sharp, six-week setback in July and August, the S&P 500 Index
gained 28.6% for the year, marking the first time the index had produced returns
of 20% or more in four consecutive years. Bond prices rose as interest rates
generally declined over the year. Returns from overseas stock markets varied
widely, with big gains in Europe, small gains in the Pacific, and losses in most
emerging markets.

U.S. STOCK MARKETS

Large-capitalization stocks--especially those of large growth companies--were
the best performers during 1998. The 50 largest stocks within the S&P 500 Index
earned more than 40%, while the return of the other 450 stocks was less than
17%. The stock market as a whole, as measured by the Wilshire 5000 Equity Index,
earned 23.4%. Small-cap stocks, represented by the Russell 2000 Index, declined
2.5% for the year.

       The huge gap between returns of large and small stocks was not the only
oddity during the year. Among large stocks there also was a large disparity in
performance between growth and value stocks. Within the S&P 500 Index, growth
stocks rose 42.2%, while value stocks were up 14.7%. The gap of 27.5 percentage
points is the largest in the 23 years that the growth and value components have
been tracked.

</TABLE>

       Stocks rose strongly during the first half of the year. But after hitting
a then-record high on July 17, the S&P 500 Index fell by 19.2% during the
following six weeks. Declines were steeper for most smaller stocks. The Russell
2000 Index fell nearly 40% from its peak in April before climbing back during
the fourth quarter.

       The summer slump in stock prices reflected several factors that raised
anxiety among investors and prompted a reconsideration of risk that extended
past stocks to bonds. Among these factors were deteriorating corporate earnings;
Russia's default on its debts; sharp swings in currency exchange rates; and
lingering economic weakness in Asia.

       Although these sources of uncertainty remained as the year went on, many
investors reacted not by abandoning stocks, but by selecting large, well-known
stocks they perceived as reliable vehicles for long-term growth. The strong
rebound in prices during the fourth quarter was due in large part to the calming
influence on jittery markets of the Federal Reserve Board's decision to cut
short-term interest rates by 0.75 percentage point.

       Technology stocks led the market's advance during 1998, rising 83%.
Investors were attracted by rapid revenue growth and a belief that consumers and
businesses will keep spending freely on computers, software, and computer
services. Speculation also played a role in the surge. Burgeoning activity on
the Internet sent many stocks, even those with no hint of profitability,
skyrocketing. The bulge in Internet stock prices prompted comparisons with such
historic asset "bubbles" as Japan's stock market in the late 1980s and the
tulip-bulb mania in Holland in the 1630s.

       Health care and utilities, especially telecommunications providers, also
soared, achieving returns of more than 43%. Both sectors benefited from rising
demand for their products and a perception that they are somewhat protected from
foreign economic troubles and foreign competition. Consumer-related stocks such
as retailers also did well, reflecting strength in consumer spending. Americans
spent almost every after-tax dollar they earned during 1998. Jobs were abundant;
unemployment fell to 4.3% by year-end.

       The worst-performing groups were two directly harmed by falling commodity
prices: oil drilling and services firms in the "other energy" category (-36%)
and materials & processing firms (-1%), such as paper, steel, and chemical
makers. Producer-durables companies, such as machinery and aircraft makers, eked
out a 2% return as companies saw falling sales abroad and rising competition at
home from foreign firms.

U.S. BOND MARKETS

The fall in interest rates during 1998 was steepest for U.S. Treasury
securities, which benefited from heightened aversion to risk among investors and
from a slight decrease in supply, thanks to a $70 billion federal budget
surplus. The low inflation rate--consumer prices were up just 1.6%--gave the
Federal Reserve the flexibility to cut short-term rates even though economic
growth was strong.

       Yields on long-term Treasury issues fell by roughly 1 percentage point,
and the 30-year Treasury bond's yield was 5.09% on December 31. Lower rates mean
higher bond prices, and the Lehman Brothers Long U.S. Treasury Index earned a
total return of 13.5%, an astounding margin of nearly 12 percentage points over
the inflation rate.

       Bonds lacking the unquestioned credit quality of Treasuries did not fare
as well, reflecting a repricing of risk and a "flight to quality" by investors
who began to feel they had been underestimating risk. One result was price
declines that nearly offset the interest earned on high-yield "junk" bonds.
However, high-quality corporate bonds and mortgage-backed securities generally
held up well. The Lehman Aggregate Bond Index, which encompasses Treasury,
mortgage, and high-quality corporate securities and has an intermediate-term
average maturity, earned a solid 8.7%.

       Yields on long-term municipal bonds declined only slightly during the
year, and by December 31 were only a tad lower than yields on long-term
Treasuries. This was striking because the interest on municipals is exempt from
federal income tax.

INTERNATIONAL STOCK MARKETS

Europe's stock markets beat even the S&P 500 Index's gaudy return, gaining 28.7%
in U.S.-dollar terms, with about 5% of the gain due to a fall in the dollar
versus most European currencies. Pacific-region stocks rose 2.6%, although it
took a fall in the dollar's value versus the Japanese yen to overcome losses in
local-currency terms. Overall, developed international markets, as measured by
the MSCI EAFE Index, earned 20.3%.

       Investors' confidence in emerging markets continued to evaporate in 1998,
and stocks in these markets fell about 25% as a group. The few bright spots
included South Korea (+141%) and the Philippines (+13%), which had suffered big
declines in 1997.

AVERAGE COUPON. The average interest rate paid on the securities held by a fund.
It is expressed as a percentage of face value.

AVERAGE DURATION. An estimate of how much a bond fund's share price will
fluctuate in response to a change in interest rates. To see how the price could
shift, multiply the fund's duration by the change in rates. If interest rates
rise by one percentage point, the share price of a fund with an average duration
of five years would decline by about 5%. If rates decrease by a percentage
point, the fund's share price would rise by 5%.

AVERAGE MATURITY. The average length of time until bonds held by a fund reach
maturity (or are called) and are repaid. In general, the longer the average
maturity, the more a fund's share price will fluctuate in response to changes in
market interest rates.

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
ratings assigned to a fund's securities holdings by credit-rating agencies. The
agencies make their judgment after appraising an issuer's ability to meet its
obligations. Quality is graded on a scale, with Aaa or AAA indicating the most
creditworthy bond issuers and A-1 or MIG-1 indicating the most creditworthy
issuers of money market securities.

BETA. A measure of the magnitude of a fund's past share-price fluctuations in
relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20 would have seen its share price rise or fall by 12% when the overall
market rose or fell by 10%.

CASH RESERVES. The percentage of a fund's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate bond
investment.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a fund's securities by credit
rating can help in gauging the risk that returns could be affected by defaults
or other credit problems.

DISTRIBUTION BY ISSUER. A breakdown of a fund's holdings by type of issuer or
type of instrument.

DISTRIBUTION BY MATURITY. An indicator of interest-rate risk. In general, the
higher the concentration of longer-maturity issues, the more a fund's share
price will fluctuate in response to changes in interest rates.

EXPENSE RATIO. The percentage of a fund's average net assets used to pay its
annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

INVESTMENT FOCUS. This grid indicates the focus of a fund in terms of two
attributes: average maturity (short, medium, or long) and average credit quality
(Treasury/agency, investment-grade corporate, or below investment-grade).

NUMBER OF ISSUES. An indicator of diversification. The more separate issues a
fund holds, the less susceptible it is to a price decline stemming from the
problems of a particular issue.

R-SQUARED. A measure of how much of a fund's past returns can be explained by
the returns from the overall market (or its benchmark index). If a fund's total
return were precisely synchronized with the overall market's return, its
R-squared would be 1.00. If a fund's returns bore no relationship to the
market's returns, its R-squared would be 0.

YIELD. A snapshot of a fund's interest income. The yield, expressed as a
percentage of the fund's net asset value, is based on income earned over the
past 30 days and is annualized, or projected forward for the coming year.

grouped and subtotaled by bond type (U.S. government and agency issues,
corporate bonds, foreign bonds, etc.); corporate bonds are further classified by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments to calculate the fund's Net Assets. Finally, Net
Assets are divided by the outstanding shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

        At the end of the Statement of Net Assets of each fund, you will find a
table displaying the composition of the fund's net assets. Undistributed Net
Investment Income is usually zero because the fund distributes its net income to
shareholders as a dividend each day. Any realized gains must be distributed
annually, so the bulk of net assets consists of Paid in Capital (money invested
by shareholders). The balance shown for Accumulated Net Realized Gains usually
approximates the amount available to distribute to shareholders as capital gains
as of the statement date, but may differ because certain investments or
transactions may be treated differently for financial statement and tax
purposes. Any Accumulated Net Realized Losses, and any cumulative excess of
distributions over net realized gains, will appear as negative balances.
Unrealized Appreciation (Depreciation) is the difference between the value of
the fund's investments and their cost, and reflects the gains (losses) that
would be realized if the fund were to sell all of its investments at their
statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. Because the fund distributes its
income to shareholders each day, the amounts of Distributions--Net Investment
Income generally equal the net income earned as shown under the Operations
section. The amounts of Distributions--Realized Capital Gain may not match the
capital gains shown in the Operations section, because distributions are
determined on a tax basis and may be made in a period different from the one in
which the gains were realized on the financial statements. The Capital Share
Transactions section shows the amount shareholders invested in the fund, either
by purchasing shares or by reinvesting distributions, and the amounts redeemed.
The corresponding numbers of Shares Issued and Redeemed are shown at the end of
the Statement. Distributions, Capital Share Transactions, and Shares Issued and
Redeemed are shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis for each class of shares. It also presents
the Total Return and shows net investment income and expenses as percentages of
average net assets. These data will help you assess: the variability of the
fund's net income and total returns from year to year; the relative
contributions of net income and capital gains to the fund's total return; how
much it costs to operate the fund; and the extent to which the fund tends to
distribute capital gains. The table also shows the Portfolio Turnover Rate, a
measure of trading activity. A turnover rate of 100% means that the average
security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Bond Index Funds comprise the Total Bond Market Index Fund, Short-Term
Bond Index Fund, Intermediate-Term Bond Index Fund, and Long-Term Bond Index
Fund, each of which is registered under the Investment Company Act of 1940 as a
diversified open-end investment company, or mutual fund. Certain of the funds'
investments are in corporate debt instruments; the issuers' abilities to meet
their obligations may be affected by economic developments in their respective
industries.

A.     The following significant accounting policies conform to generally
accepted accounting principles for mutual funds. The funds consistently follow
such policies in preparing their financial statements.

       1. SECURITY VALUATION: Bonds, and temporary cash investments acquired
over 60 days to maturity, are valued using the latest bid prices or using
valuations based on a matrix system (which considers such factors as security
prices, yields, maturities, and ratings), both as furnished by independent
pricing services. Other temporary cash investments are valued at amortized cost,
which approximates market value. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value.

       2. FEDERAL INCOME TAXES: Each fund intends to continue to qualify as a
regulated investment company and distribute all of its income. Accordingly, no
provision for federal income taxes is required in the financial statements.

       3. REPURCHASE AGREEMENTS: Each of the Vanguard Bond Index Funds, along
with other members of The Vanguard Group, transfers uninvested cash balances
into a Pooled Cash Account, which is invested in repurchase agreements secured
by U.S. government securities. Securities pledged as collateral for repurchase
agreements are held by a custodian bank until the agreements mature. Each
agreement requires that the market value of the collateral be sufficient to
cover payments of interest and principal; however, in the event of default or
bankruptcy by the other party to the agreement, retention of the collateral may
be subject to legal proceedings.

       4. DISTRIBUTIONS: Distributions from net investment income are declared
daily and paid on the first business day of the following month. Annual
distributions from realized capital gains, if any, are recorded on the
ex-dividend date.

       5. OTHER: Security transactions are accounted for on the date securities
are bought or sold. Costs used to determine realized gains (losses) on the sale
of investment securities are those of the specific securities sold. Premiums and
discounts on debt securities purchased are amortized and accreted, respectively,
to interest income over the lives of the respective securities.

B.     The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the funds under methods approved by the Board of
Trustees. Each fund has committed to provide up to 0.40% of its net assets in
capital contributions to Vanguard. At December 31, 1998, the funds had
contributed capital to Vanguard (included in Other Assets) of:

C.     The Total Bond Market Index Fund offers two classes of shares, the
Investor Shares and the Institutional Shares. Institutional shares are designed
primarily for institutional investors that meet certain administrative and
servicing criteria and have a minimum investment of $10 million. Investor
shares are offered to all other investors. Both classes of shares have equal
rights as to assets and earnings, except that each class bears certain
class-specific expenses related to its shareholder activity. For the year ended
December 31, 1998, class-specific expenses represented an annual rate of 0.14%
and 0.04% of average net assets of the Investor Shares and Institutional
Shares, respectively. Income, expenses not attributable to a specific class,
and realized and unrealized gains and losses on investments are allocated to
each class of shares based on its relative net assets.

        The funds' custodian bank has agreed to reduce its fees when the fund
maintains cash on deposit in the non-interest-bearing custody account. For the
year ended December 31, 1998, custodian fee offset arrangements reduced
expenses for the Total Bond Market Index Fund, Short-Term Bond Index Fund,
Intermediate-Term Bond Index Fund, and Long-Term Bond Index Fund by $18,000,
$2,000, $4,000, and $2,000, respectively.

</TABLE>

        During the year ended December 31, 1998, the Total Bond Market Index
Fund realized $854,000 of net capital gains resulting from in-kind
redemptions--in which shareholders exchanged fund shares for securities held by
the fund rather than for cash. Because such gains are not taxable to the fund,
and are not distributed to shareholders, they have been reclassified from
accumulated net realized gains to paid in capital.

        Capital gains distributions are determined on a tax basis and may differ
from realized capital gains for financial-reporting purposes due to differences
in the timing of realization of gains. At December 31, 1998, the Total Bond
Market Index Fund, Short-Term Bond Index Fund, Intermediate-Term Bond Index
Fund, and Long-Term Bond Index Fund had capital gains of $15,248,000,
$2,651,000, $4,101,000, and $444,000 available for distribution, respectively.
The Total Bond Market Index Fund and Intermediate-Term Bond Index Fund used
capital loss carryforwards of $12,406,000 and $3,553,000, respectively, to
offset taxable gains realized during the year ended December 31, 1998, reducing
the amount of capital gains that would otherwise be available to distribute to
shareholders.

        Security loans are required to be secured at all times by collateral at
least equal to the market value of securities loaned; however, in the event of
default or bankruptcy by the other party to the agreement, retention of the
collateral may be subject to legal proceedings. Cash collateral received is
invested in repurchase agreements.

REPORT OF INDEPENDENT
ACCOUNTANTS

[PHOTO]

To the Shareholders and Trustees of
Vanguard Bond Index Funds

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Total Bond Market Index Fund, Short-Term Bond Index Fund, Intermediate-Term Bond
Index Fund and Long-Term Bond Index Fund (separate funds of Vanguard Bond Index
Funds, hereafter referred to as the "Funds") at December 31, 1998, the results
of each of their operations for the year then ended, the changes in each of
their net assets for each of the two years in the period then ended and the
financial highlights for each of periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

                             The Vanguard Group is
                            named for HMS Vanguard,
                       Admiral Horatio Nelson's flagship
                          at the Battle of the Nile on
                          August 1, 1798. Our founder,
                         John C. Bogle, chose the name
                        after reading Nelson's inspiring
                      tribute to his fleet: "Nothing could
                          withstand the squadron . . .
                       with the judgment of the captains,
                      together with their valour, and that
                        of the officers and men of every
                 description, it was absolutely irresistible."

                        celebrated his 100th birthday on
                           July 23, 1998. Mr. Morgan,
                        a true investment pioneer, died
                        six weeks later on September 2.

                       The Vanguard Group's oldest fund,
                         was incorporated by Mr. Morgan
                      70 years ago, on December 28, 1928.
                            The fund was named after
                            the Duke of Wellington,
                             whose forces defeated
                           Napoleon Bonaparte at the
                           Battle of Waterloo in 1815
